Structure are supported mainly by a skeleton, or frame, of wood, steel, or reinforced concrete rather than by load-bearing walls. Rigid frames have fixed joints that enable the frames to resist lateral forces; other frames require diagonal bracing or shear walls and diaphragms for lateral stability.
